pacity and with the same driving style. If you drive more efficiently this value
can increase.
AdBlue ®
range - drive distance in km which can be covered with the existing
AdBlue ®
tank capacity and with the same driving style. If you drive more effi-
ciently this value can increase.
Average fuel consumption - is calculated continuously since the last time the
memory was deleted. After erasing the memory, no data will appear for the
first 100 m driven.
Current fuel consumption - when the vehicle is stationary or slowly moving,
the fuel consumption is displayed in l/h (--,- km/l appears on models for some
countries).
Oil temperature - if the temperature is lower than 50 °C or if there is a fault in
the system for checking the oil temperature, the symbols are displayed.
Warning when the preset speed is exceeded - allows the setting of a speed
limit where, if exceeded, an acoustic warning signal and a warning message
appears on the display of the instrument cluster.
